I am sorry that my first posting was misleading.

In the above article I'm referring to the dealer of the system, who knew from
previous experience that the chip didn't work in this particular system,
AND that the Intel chips work OK. (this is confirmed!)

This lead me to the same conclusion as Stephen M. Smith : it IS peculiarities
with this particular board! (although as far as we have seen the board works 
fine with DOS and OS/2 in all other respects)

The intention with my initial posting was to warn you: It is possible to find systems in which the industry standard Intel chips work OK, but the chip from Cyrix do NOT!
